γ-(2,3-Epoxypropoxy)propyltrimethoxy silane surface modified layered double hydroxides (KH560-LDHs) were prepared and used to improve the ultraviolet ageing resistance of asphalt. The results of X-ray photoelectron spectrometry (XPS) indicated that KH560 has been successfully grafted onto the surface of LDHs. The agglomeration of LDHs particles notably reduced after KH560 surface modification a...

A new composite membrane system, Geo-SealTM, has been developed that offers exceptional chemical resistance for use as a vapor barrier at brownfield sites. Data generated in controlled laboratory conditions indicate the composite membrane to have < 0.2X the volatile organic compound partitioning when compared to spray applied latex/asphalt vapor barriers. More importantly, data generated under ...

The experience of developed countries shows that the development road network and transport infrastructure determines intensity economic ties is one most important conditions for state’s economy. Optimization composition production technology asphalt concrete mixture – basis paved roads, great importance, both from an environmental point view. directly (during process at plants) indirectly deli...

Asbuton is a natural asphalt material that has greater resilience and elasticity compared to extraction asphalt. When exposed the sun rain, asbuton strong solid nature, texture also elastic so it less likely crack. One of wastes continues be used in field road pavement plastic waste this research, which type polyethylene terephthalate (PET). A lot generated every year but little can used. This ...

in this study, an artificial neural network was developed in order to analyze flexible pavement structure anddetermine its critical responses under the influence of standard axle loading. in doing so, more than 10000four-layered flexible pavement sections composed of asphalt concrete layer, base layer, subbase layer, andsubgrade soil were analyzed under the impact of standard axle loading. pave...
