The bituminous pavement rehabilitation alternatives are mainly overlaying, recycling and reconstruction. In the recycling process the material from deteriorated pavement, known as reclaimed asphalt pavement (RAP), is partially or fully reused in fresh construction. Some of the advantages associated with pavement recycling are (i) less user delay (ii) conservation of energy (iii) preservation of...

In recent years, Reclaimed Asphalt Pavement (RAP) has become very popular in pavement construction due to its benefits the economy and environment. The present study investigates feasibility of employing Waste Cooking Oil (WCO) Engine (WEO) as rejuvenators blended with reusable asphalt binder through physical rheological properties at high intermediate temperatures. Examined conventional WCO-an...

Technology in transportation used available resources to make it safe, fast, suitable, easy, economic, and environmental transport people goods. Olive Husk became an problem as waste materials especially the Middle East where huge quantities are found. The objective of this research is investigate effect addition Ash (OHA) on properties asphalt concrete mixtures. Marshall Test was perform mixtu...

Bio-asphalt is a binder composed of bio-oil and petroleum asphalt under certain conditions. In this study, sludge (wt 10%) was added into matrix to prepare bio-asphalt for the first time. The effects on performance essence interaction between components were investigated using test, molecular dynamics (MD) simulation, density functional theory (DFT). Chemical analysis showed that ester compound...

Processing of the local Mubarek oil sludge with subsequent production a binder for foundation highways and roofing. Methods utilization were used to obtain binder. Innovative technology asphalt pavement by oxidation method has been developed. Investigations chemical composition roads elemental analysis dehydration its homogeneous state are presented.

To explore the applicability of steel slag porous asphalt mixture, interaction capability and microscopic interfacial mechanism between asphalt-binder aggregate-filler were investigated in this laboratory study. These objectives accomplished by comparing analyzing differences basalt aggregates interacting with asphalt-binder. The study methodology involved preparing mortar to evaluate penetrati...
