Abstract

A section of a highway carrying heavy traffic was located on fill of height ranging from 2-3m. The total thickness of the pavement was of the order of 550mrn and consisted of bituminous surfacing, granular base and sub base. Although the expected life of the pavement was ten years, severe distress including transverse deformations and cracking of the pavement was experienced within one year after traffic started plying on this section. However, the adjoining stretch, built at the same time, continued to perform satisfactorily. A study consisting of comprehensive testing program was taken up to establish the causes of distress. Particular attention was paid to the properties of fill material. It was found that failure of the pavement was due to the poor quality of the fill material used for construction of the embankment. Some of the peculiar properties of these fill materials are discussed in this paper.

Failure of Highway Fill and Investigation into Its Causes

St. Louis, Missouri

A section of a highway carrying heavy traffic was located on fill of height ranging from 2-3m. The total thickness of the pavement was of the order of 550mrn and consisted of bituminous surfacing, granular base and sub base. Although the expected life of the pavement was ten years, severe distress including transverse deformations and cracking of the pavement was experienced within one year after traffic started plying on this section. However, the adjoining stretch, built at the same time, continued to perform satisfactorily. A study consisting of comprehensive testing program was taken up to establish the causes of distress. Particular attention was paid to the properties of fill material. It was found that failure of the pavement was due to the poor quality of the fill material used for construction of the embankment. Some of the peculiar properties of these fill materials are discussed in this paper.
