Analysis of the Causes of Road Damage

Abstract

The background of this research is the existence of roads is needed to support the rate of economic growth, agriculture, social, cultural and other sectors. While in reality, the condition of road construction is often not followed by good maintenance, causing various kinds of problems. There are alternative solutions to repair road pavements which can be classified into 2 types, namely functional repairs and structural repairs. This research is a qualitative descriptive research on secondary data collection, which aims to study the literature through the collection, comparison and inventory of previous studies on road pavement damage, the aspects that cause it, and effective countermeasures to overcome it and provide an overview of road pavement damage and aspects that cause the limitations of several areas that are the object of research. for growing crops. and cyclic triaxial undrained tests were performed on Shanghai clay through simultaneously varying the torsional shear stress and the normal stresses. Experimental results show that the accumulated undrained responses of clay at different stress levels can be described by the shakedown approach. The permanent strain and energy dissipation were used to classify the accumulated deformation patterns, including plastic shakedown, cyclic plastic creep and ratcheting (incremental instability). For the plastic shakedown, the IPC (increment per cycle) of permanent axial strain becomes negligible and the IPC (area of hysteretic loop per cycle) of energy dissipation tends to reach a low constant level after cycling. For the cyclic plastic creep, the IPC of permanent axial strain (plastic strain increment per cycle) and the IPC
