MODEL VALUE OF RESIDUAL STRENGTH OF CONCRETE ASPHALT PAVEMENT CONSEQUENCES OF SOAKING OF RAINWATER AND SEAWATER BY CONTINUOUS AND PERIODIC METHODS

Abstract

High rain intensity and limited draninase capacity result in high waterlogging on the  road surface for a long time.   After dry inundation,  the pavement surface undergoes a bond between the aggregate and loose asphalt.   This loose condition, when crossed by vehicles,  causes cracks and holes so that the road is damaged.   In addition,     large-scale waterlogging can cause  groundwater located below the  soil surface to become saturated.  The research method  is an  experimental laboratory with the help of  descriptive statistics in analyzing data to find out an overview of the   characteristics of concrete asphalt mixture materials. Penelitian aims to: Knowing the relationship between variations in soaking  duration  to the  durability performance of  asphalt concrete mixtures, Evaluating differences in residual strength index values  due to  length soaking by using seawater and  rainwater  with continuous and periodic mrtode,  and Determining  the  relationship  model between the  Residual Strength Bonding of  the asphalt mixture to  time of soaking seawater and rainwater. The residual  strength bond value (IKS) is greatly influenced by  the  soaking time, where the  longer  the  concrete asphalt  issoaked, the significantly  lower   the  IKS  value. As for the Modelh the difference between the Residual Strength Index against the bath time is a polynomial model.
