Stripping is one of the major distresses within asphalt concrete pavements caused due to penetration water interface asphalt-aggregate matrix. In this work, grade cement (40-50) was mixed with variable percentages three types additives (fly ash, fumed silica, and phosphogypsum) obtained an modified resist effect stripping phenomena .The specimens have been tested for physical properties accordi...

The Km-18 of Padang Bypass Road is an Arterial road class III-A. This burdened by heavy vehicles which carrying loads that exceed the permitted capacity. activity can lead to damage and a reduction in life. study aims analyze effect traffic capacity on conditions, including remaining life pavement degree damage. primary data used conditions such as discharge surface grains, potholes, grooves. S...

Abstract Bridge resilience is a newly proposed bridge design criterion that involves robustness, redundancy and reparability targeting on the rapidity of functionality restoration after suffering extreme actions long-term durability deterioration. It stipulates lower probability reaching ultimate limit state or strength state, which have been only partly involved in codes around world. In AASHT...

Pre-stressed steel-concrete composite beams are widely used in bridges around the world. Loads during service life of may cause failure form fracture studs near ends bridge girders. The effect stud on residual static capacity and fatigue girders is not well investigated. Therefore, this study presents numerical investigations into effects progressive shear connectors performance remaining post-...

Abstract Sedimentary soil is made up of deposits that are the consequence weathering rocks have already been deposited elsewhere by various natural processes, including water, wind, and others. A location with sedimentary Bili-bili Dam in South Sulawesi Province's Gowa Regency. at this quite abundant has not used general, so it can be investigated for its use, namely stability against influence...

Whatever vehicle is traveling, it needs to stop in order arrive road users their different goals. In most universities, parking becomes an important campus resource, for being as a place come frequently and spend long period. Now days problems increase with repaid growth of car ownership. So traffic impact can be consider major source contention within any community raise additional costs well ...

PROBLEM STATEMENT When designing and evaluating asphalt pavements, engineers must have an understanding of how the pavement materials will react to the stresses and strains of vehicle loads at varying temperatures. When a load is applied to asphalt concrete at a certain temperature, to what degree will the pavement "bounce back" to its original height? Pavement designers predict this spring-lik...

Enhancement in fatigue performance of welded joints by Ultrasonic Impact Treatment (UIT) was evaluated in large-scale specimens having a nominal yield strength of 345 to 690 MPa. Eighteen rolled-beam specimens having welded details at cover plates and transverse stiffeners and eight built-up specimens having only transverse stiffener details were fatigue tested after treating them by UIT. A par...
