The mixture of asphalt sand or often called as LATASIR (a thin Layer of asphalt Sand) is often used on the streets as light as local roads or road environment, in order to restrain the rate of water so as not to enter into pores in it. This mixture consists only of fine aggregate or sand or a mixture of both, so of coarse aggregate is not found in its alloy, so have the resilience of the Groove (rutting) are low and cannot be used on roads with heavy traffic or the area slopes. To improve the quality of asphalt mixture Latasir then do the addition of waste tire rubber out of the motor. This research was conducted with the marshall test asphalt plan levels, with 7%, 8%, 9%, 10% and 11% in advance. After obtained the value levels of Optimum Asphalt (KAO), then do the test with the addition of marshall rubber tyres outside the motor of 1%, 2%, 3%, 4% and 5% against weight. The research results obtained a value of 9.8%, KAO then conducted testing of marshall by using a variation of the rubber tyres outside the motor changes characteristic of Marshall, the degree of suppleness and durability is better, but there is a cavity the air that many great VIM or value, so that the value of the VFA became small. From all levels of rubber in asphalt has a great degree of flexibility in rubber 3%, but that filled the whole terms of the 2010 revision 3 technical specifications on levels of 1.5% rubber.Keywords: Latasir Mixture, KAO, Waste Rubber Tyres Outside Motor, Marshall

Laston is a mixture of coarse aggregate, fine aggregate, and filler with a binder under the temperature of 145-155oC with the composition being studied and regulated by technical specifications. Laston is also known as AC (Asphalt Concrete).Laston itself is commonly used in Indonesia with continuous gradations used for heavy traffic loads. To get the addictive material is not easy and the material is expensive. Therefore, it is necessary to find alternatives to the cellulose fiber. Water hyacinth is a water weed that once grow and develop, it has high cellulose fiber content, which is about 60%.For that, done a research to add a hot asphalt mixture material that aims to improve the quality of mixed result. The selected material is natural water hyacinth. The method used is trial and error with reference of SNI 03-1737-1989. Variations used are 3%, 5%, and 7% of the asphalt weight, asphalt level used Is 5.61%.The result of this study is Marshall evaluation where the greatest score obtained for stability is 1325 kg,  Flow is 3.73 mm, Quotient Marshall is 401.02 kg/mm, VMA is 66.30%, VFWA is 19.25%, and VIM score is 54.35 %. With this result, the asphalt mixture can not be used because the results of VMA, VFWA, and VIM have not been suitable on specification of SNI 03-1737-1989.  Keywords: Laston, Asphalt Concrete, Water Hyacinth, SNI 03-1737-1989.

Because of the heating limitation of old pavement and the restriction of climate, the quality of hot in-place recycled pavement was different to control. The warm m,ix asphalt technology was introduced to improve the heterogeneity and compactness of the hot in-place recycled pavement and decrease its construction temperature. The compaction characteristics of warm in-place recycled asphalt mixture were analyzed and its molding temperature was determined through the Marshall test. The pavement performance of warm in-place recycled asphalt mixture was analyzed whose results indicated that the introduction of warm mix asphalt technology was able to improve the compactness, the high temperature stability and water stability of hot in-place recycled asphalt mixture and reduce the influence of environment over its construction quality. A warm in-place recycled engineering of Shian expressway was introduced to verify the feasibility of warm in-place recycling technology which demonstrated that the warm in-place recycling technology was able to improve the heterogeneity and compaction quality of the recycled pavement and weaken the environmental pollution.

The compressive characteristics of the steel-slag concrete were investigated through an experimental test. The term “steel-slag concrete” in this research work was defined as a kind of concrete using steel-slag material as a coarse aggregate replacement. Three types of the steel-slag concretes were examined under compression as follows: XT01, XT02, XT03 with their cement/water ratios of 1.76, 2.00, 2.21, respectively. The coarse aggregate used in producing concrete was steel-slag material, while the fine aggregate was traditional river sand; the ratio of coarse aggregate to fine aggregate was kept constant at a value of 1.98. Firstly, the age-dependent compressive strength of the steel-slag concretes were investigated up to one year; it was clear that the concrete strength increased rapidly in 7 days, then more and more slowly after that. Secondly, the modulus of elasticity and Poisson’s ratio of the steel-slag concretes were explored at the 28-day age. Thirdly, there was an important size and shape effect on the compressive strength of the XT02, and its significance of brittleness in failure was analytically analyzed. Lastly, the effects of water amount added in the XT02 on its compressive strength and slump were evaluated at the 28-day age.
