Marshall Stability

In pavement structures that are often submerged by water, the damage to pavement is often caused by the loss of bonds or adhesions between the aggregate and asphalt, the type of damage that occurs due to the loss of adhesion between the aggregate and asphalt is the exfoliation of asphalt granules so that the road is cracked and corrugated. To reduce the release of aggregate granules and improve the bond between aggregates and asphalt can be made with the addition of anti-exfoliating additives or antistripping agent additives. This study aims to analyze the performance of wear-coated concrete asphalt mixture (ACWC) with the addition of antistripping additives. Antistripping agents used in this study were Zycotherm, Morlife and Adhebit with variations of 0.1% addition, 0.3% and 0.5% of the weight of asphalt mixture. The results of this study showed that ACWC mixture with the addition of Zycotherm additives resulted in optimum Marshall stability and increased durability at 0.5% and Adhebit additives at 0.3% levels, while in Morlife additives although at 0.3% levels were able to show optimum marshall analysis in terms of increased durability did not show expected performance.

Fiber reinforcement as an available attempt has been proved to be effective in improving the toughness of asphalt concrete and is becoming a new method for highway maintenance. When fiber modified asphalt mixture is used as the surface course of a reconstructive pavement, the interface bonding property between top and lower layers seems to become a crucial factor in the road performance of the long lasting pavement. The primary objective of the research is to study the influence of fiber inclusions on the interfacial shear property of the pavement. With the purpose of discussing the shear strength of the interface between Bonifiber modified asphalt mixture top layer and the normal asphalt mixture layer，the laboratory shear test was developed on MTS-810. Four kinds of double-layered cylindrical specimens were made to simulate the different pavement structures. Test results show that the overlaying with Bonifiber modified asphalt mixture improves not only the general road performance but also the interface property. It is concluded that, the interface property of pavement with fiber reinforced top layer behaves much better than that with normal asphalt concrete one.

The repetitive traffic loadings that the road experiences during its service life, combined with temperature fluctuations, cause rutting, fatigue and other forms of deteriorations, which ultimately degrade the performance and durability of pavement structures. According to test procedure specified by ASTM D1559 several hot asphalt mixture were prepared, the aggregate blend made by Job mix formula to obtain the percentage of mix material is give Hot-bin one is 26%, Hot-bin two is 23%, and Hot-bin three 51% where hot-bin one is (20-13.2mm), hot-bin two (13.2-5.0mm) and hot-bin three (5.0-0.00mm). The result of Marshall Test on mix design for hot asphalt mixture, for wearing coarse were conclude that the material used for mix design is good, which gives Marshall stability, 12.57 KN with optimum bitumen content of 5.2% (by weight of total aggregate). Hence the quality of aggregate is good but the influence of other factors such as poor drainage courses, level of ground water table, Varity of geological materials along the road rout and poor construction methodology caused the defect. The flow result of the Marshall mix design gives as 3.6 % which is approach of upper limit of specification 4%, So when flow become high in the mix it result long term deterioration of asphalt performance, hence the pavement condition along the study area has been affected by different failure types such as cracks, surface defect and disintegrating from site observation may result of this.

This study mainly uses PFC (particle follow code) to simulate the void characteristics of permeable asphalt mixture, and uses these to simulate the silting process. Then, a tire drop test was used to evaluate the noise reduction performance of permeable asphalt concrete. Finally, a self-made ring rutting test machine was used to simulate the silting process. Through experiments, the following conclusions were obtained: 1. The critical size of the sludge particle size is 0.3 mm–0.6 mm. 2. The quality of the water-permeable asphalt concrete specimens increased by 13% before and after silting, and the porosity of the specimens finally decreased from about 20% to about 8%. The water-permeable function only retained less than 20% of the original, and the water-permeable function was basically lost. 3. By measuring the road noise detection, it was found that the road noise is directly proportional to the degree of blockage of the permeable road. Compared with the original road with a perfect permeable function, the road noise of the completely blocked road increased by about 4 decibels. This study reveals the silting process of permeable asphalt mixture and the key particle size of the silt, which is of great significance for the detection, cleaning and maintenance of permeable asphalt pavements.

Durability of hot mix asphalt (HMA) against moisture damage is mostly related to asphalt-aggregate adhesion. The objective of this work is to find the effect of nanoclay with montmorillonite (MMT) on Marshall properties and moisture susceptibility of asphalt mixture. Two types of asphalt cement, AC(40-50) and AC(60-70) were modified with 2%, 4% and 6% of Iraqi nanoclay with montmorillonite. The Marshall properties, Tensile strength ratio(TSR) and Index of retained strength(ISR) were determined in this work. The total number of specimens was 216 and the optimum asphalt content was 4.91% and 5% for asphalt cement (40-50) and (60-70) respectively. The results showed that the modification of asphalt cement with MMT led to increase Marshall stability and the addition of 6% of MMT recorded the highest increase, where it increased by 26.35% and 22.26% foe asphalt cement(40-5) and(60-70) respectively. Also, the addition of MMT led to increase moisture resistance of asphalt mixture according to the increase in TSR and IRS. The addition of 4% and 6% of MMT recorded the highest increase in TSR and IRS for asphalt cement (40-50) and (60-70) respectively, where they increased by 11.8% and 17.5% respectively for asphalt cement (40-50) and by 10% and 18% respectively for asphalt cement (60-70).

Engineers are constantly trying to improve the performance of the flexible pavements. The main surface distress types which cause maintenance and disruption are rutting and fatigue cracking. For solving these problems, many studies have been carried out until now, ranged from changing gradation to adding polymers and fibers to asphalt mixture. In this study, polypropylene additive was selected as fiber additive because of low costing and having good correlation with asphalt pavement. Three type of polypropylene additive in the length 6, 12 and 19 mm were selected and used at five different percentages in the asphalt concrete mixture. Asphalt specimens were analysed by Marshall Analysis and finally tested by Marshall Stability apparatus. Adding polypropylene increased Marshall Stability (38%), and decreased Flow (39%). These results show that polypropylene can be helpful for increasing pavement life.
