Investigating causal factors of road damage: a case study

Abstract

High rainfall leads to flood vulnerability and potentially leads to the failure of road pavement which affects the economic loss for the people. However, such road pavement failures need to be studied more deeply to be able to distinguish whether the failure is solely due to flood natural disaster or other factors, such as overloading and poor construction quality. This research is urgently needed because up to now there is no tool for assessing pavement failure as a tool of decision-making system that is able to distinguish road pavement failure causal factors into category of natural disaster or human negligence factors in accordance with the definition of building failure in Indonesia Law no. 2 year 2017. Assessment of the causal factor of failure is very important because it is closely related to the determination of the parties who must be legally responsible. This research intends to develop methods for assessing the damage and failure of pavement as a tool of rapid and accurate decision-making system to determine the factors of pavement failure. To obtain accurate results, a case study was taken on Kendal Timur road to enable a deep evaluation of the factors that causing failure on the road. The results showed that many factors involved in causing the failure of the road, such as un-functional drainage channel, uncontrolled overload due to the closing of weigh stations around the road, and also low quality of road maintenance work so that repeating similar road damages occurred in the not-too-distant future. Based on functional and structural failure analysis, as much as 71%, 10% and 19% of the road were in failed, critical and not-failed conditions, respectively.

Asphalt Elasticity Modulus Comparison Using Modified Laboratory LWD Against UMMATA Method

“…Several variables influence the deflection value of this nondestructive test, including temperature, moisture content, kind of component of the pavement layer, operator abilities, and type of equipment [20]. Typically, the equipment used for this test consists of static or dynamic loads that are given to the road surface through a load plate [21], while other tests are conducted by directly measuring the amount of the deflection [22].…”

Use of UAV-based photogrammetry products for semi-automatic detection and classification of asphalt road damage in landslide-affected areas

“…As part of worldwide applied road maintenance and rehabilitation procedures, the International Roughness Index (IRI), the Pavement Condition Index (PCI) and the Pavement Serviceability Index (PSI) are the mostly used indicators of pavement structural and operational performance under usual stress conditions. These indices are based on the road roughness, distress, bearing capacity and skid resistance (George et al, 1989;Hatmoko et al, 2019;Pawar et al, 2018;Ragnoli et al, 2018;Tan and Li, 2019).…”

The Main Impacts of Infrastructure Works on Public Roads

“…They are generally not designed for the flow of relocated vehicles and sized for heavy vehicle traffic, mainly impacting residents. It is worth noting that overloading or overloading significantly impacts the achievement of the road project's lifetime [49]. Upon completion of the work, the final results of the paving service and the restoration of sidewalks and curbs are also important factors in the perception and association of damage relative to infrastructure works.…”
