Combined Lime–Cement Stabilization for Longer Life of Low-Volume Roads

Abstract

Low-volume roads are an important part of the world's transportation infrastructure and a direct cause of the socioeconomic development of small city and rural communities. Construction, maintenance, and rehabilitation of these roads are major tasks and require a major part of the public works budget. Better design and construction methods can prolong pavement service life and result in lower maintenance and rehabilitation costs. This paper presents a research study done for the city of Arlington in north Texas to stabilize road subsoils with a combined lime and cement stabilizer, which in turn is expected to enhance service life of the roads. Both laboratory tests on stabilized soil mixtures and field performance data are analyzed and presented.
