This study presents the use of waste polythene derived as carry bags from kitchen waste and pond liner polyethelene as LDPE and bottle caps as HDPE as an additive in flexible pavements. In this study we will also add a fix percentage of zykotherm.  Purposes of using above materials are to utilize environmentally unacceptable waste material and to develop a better material mix to resist increased traffic load and temperature effect resulting cracks in the pavement surface. In the proposed study the plastic waste will be cleaned and cut into a size such that it passes through 2-3mm sieve using shredding machine. In this study Dense Bituminous Macadam (DBM) mix will be proposed to prepare by using plain bitumen as a control specimen and bitumen mixed with LDPE 2% and 4% & HDPE 2%, 3%, 4%, 5%) as by weight, with fixed percentage of Zykotherm as 1.5% by weight.Bitumen content is 4.5% by weight for all specimen. The Marshall Stability test, Penetration Test, and softening point test, were conducted on control and modified DBM mixes.

In Buton Island, an island located in South-East Sulawesi Island in Indonesia is found about 700 million tons natural rock asphalt (NRA) which have not been maximally utilized yet. Buton-NRA contains 20 to 30% of bitumen. This paper reported the first part of the research on utilizing of Buton-NRA as additive of bitumen binder in hot mix asphalt (HMA) mixtures. Amount of 15, 20, 25, 30, 35, 50, and 65% of very fine of Buton-NRA was added into the bitumen, resulted Buton-NRA-Bitumens binder. Penetration and softening point test was conducted to get penetration index (PI) value, an index to determine the temperature susceptibility of the binder. The results show that the Buton-NRA-Bitumens binder has low temperature susceptibility. Use as binder in HMA mixtures also shown that the Buton-NRA-Bitumens binder can improve the performance of the mixtures. Marshall Stability and stiffness of the mixtures is higher compare to that of base bitumen binder, especially Buton-NRA-Bitumens binder with 50% of Buton-NRA, Marshall Stability reach 2374kg and stiffness 311kg.mm, while HMA mixtures with base bitumen (0% Buton-NRA) only has 1294kg of Marshall stability and 169kg/mm of stiffness.

The influence of combination of low density polyethylene (LDPE) and petroleum resin on asphalt was investigated by analyzing the change of its penetration, ductility, softening point and viscosity. The results show that petroleum resin can significantly increase the viscosity of PE modified asphalt, which results in the improvement of the asphalt’s waterproof ability and anti-rutting performance in a certain degree. However, the ductility and softening point were negatively affected due to the addition of the petroleum resin. Through analyzing the penetration indexes, an optimal dosage of 8% PE and 5% petroleum resin can be determined, respectively.

Reclaimed Asphalt pavement (RAP) is a C&D waste originating from the reclamation of asphalt pavement which has completed its service life. Using RAP would potentially reduce reliance on primary aggregates and lowers the environmental impact of construction. The present study is an attempt made to utilize RAP judiciously as a bound base course of the flexible pavement. Natural coarse aggregates were replaced by RAP in proportions of 50% & 100% with & without Warm Mix Asphalt (WMA), for production of bound-base course mixes. To ensure the long run performance, the aging condition was simulated in the laboratory and mechanical properties such as Marshall Stability, Tensile Strengths, Marshall Stability Retained, Indirect Tensile Ratio, rutting resistance, Fatigue life, and abrasion resistance were considered. With the incorporation of 50-100% coarse RAP, the Marshall Stability, rutting resistance and abrasion were found to be improved by 30-32%, 43-104% and 11-17% respectively. Similarly, total cost saving is about 15-35%, which is quite significant. However, the addition of WMA enhanced the cost by 3-4%, which is insignificant when combined with RAP, furthermore, the reductions in fume emission enhance the sustainability aspect of the technology.

The present study deal with the utilization of PET waste in Bituminous Concrete prepared with modified bitumen. The detailed analysis will be carried out to assess the physical and strength characteristic of prepared BC mix as per the Indian Standards. Modified bitumen used is CRMB -55 which is a binder obtained from the recycling of rubber tyre. Modified bitumen is temperature susceptible and also increases the fatigue life of pavement under the heavy traffic load. The study involved in the evaluation of more than one modification in bituminous mixes such as CRMB -55 is itself modified binder while modification has been done in the aggregate blend by addition of plastic. However, a combination has not yet been tried. The Marshall Stability test was performed to assess strength characteristics. The Marshall Stability values increase with the amount of PET and maximum stability was obtained at 6% by weight of the binder. The considerable increment was observed in Stability value with PET 6% dosage as 18.99%.

Nowadays, road damage issue become the norm due to increment of traffic load and traffic volume. It shortens the service life of asphalt mixtures and increase the cost of maintenance. One way to reduce the issue is by using polymer additive in asphalt mixture. Treated Plastic is one type of polymer additive made of plastic bag (Polyethylene). The main purpose of this research is to determine the improvement of asphalt mixture’s performance incorporating Treated Plastic (TP) as additive in terms of stability, stiffness, fatigue cracking, stripping and rutting. The mechanical properties of asphalt mixes that include various percentages of TP (0%, 0.25%, 0.5%, 0.75%, 1%, 2% and 3%) were calculated and assessed with laboratory tests. 0.75% by weight of total mix of TP was found to be the optimum amount. The outcomes were analyzed by Marshall Stability and Flow, Resilient Modulus, Tensile Strength Ratio and Hamburg Wheel Tracker test. As the results shown, the addition of TP gave significant improvement to the stability and stiffness of asphalt mixture. 0.75% of TP was selected as the optimum percent content with percent improvement about 100, 73 and 25% for fatigue cracking, rutting and stripping resistance respectively. Hence, 0.75% of TP improved the resistance of rutting and stripping but susceptible to fatigue cracking.

Polyphosphric acid (PPA) modified asphalt binders were produced in the laboratory using one base asphalt and four levels of PPA contents (0.6%, 1.0%, 1.5% and 2.0% by weight of base asphalt). Penetration test, softening point test, rotation viscosity test, creep test with bending beam rheometer (BBR) and four components test were carried out to study the performance of PPA modified asphalt binders and possible modification mechanism. The results indicate that the high-temperature performance of PPA modified asphalt binders are obviously improved and temperature susceptibility are decreased, but the low-temperature performance slightly decline compared with base asphalt. The PPA content has a very significant effect on softening point whereas it has no significant influence on low-temperature performance according to variance analysis (ANOVA). Finally, four components test reveals that the primary modification mechanism of PPA is the change of chemical composition of asphalt binder.

Deviatoric Stresses

The design of flexible pavements is based on the empirical approach and in some cases on the empirical-rational approach. Funds are being invested in developing new design methods that will principally be based on the mechanistic-rational approach. A procedure for characterizing clayey subgrade materials to provide the properties needed by the new methods is presented. The procedure addresses the following elements: first, the material should be brought to the condition that prevails under pavements. Sample preparation and a soaking procedure to simulate field condition are described. Second, after about 10 days of sample conditioning, the material is tested under repetitive loading to provide both resilient and permanent properties. In clayey soils, two samples are tested under different deviatoric stresses and for 10,000 to 100,000 load repetitions. The stress level should correspond to the stress induced by overburden and traffic load. Tests are conducted on a swelling clay, and the results are analyzed. It is seen that (a) the proposed procedure for sample conditioning is appropriate for Israeli climatic conditions, but it can be changed to fit other climatic conditions; (b) the stress level in subgrades is relatively low, so the behavior of the clayey materials can be fairly well described by linear elastic theory; and (c) the total deformation increases either linearly or exponentially with number of load repetitions (in a log-log scale).
