Full-depth reclamation and cement strengthening has been used successfully to dry and strengthen granular pavements. However, some thin pavements fail due to severe wetting-up of the subgrade, thus requiring additional substructure strengthening and (or) drainage systems. This research investigated the laboratory characterization and in situ field mechanical behaviour of full-depth reclaimed and cement-stabilized granular materials in conjunction with a woven geotextile and sand drainage system. This research showed that the integration of cement-stabilized reclaimed granular materials with a geotextile separation layer and sand drainage system significantly improved the mechanical primary response and climatic durability properties of the reclaimed road structure. The cement-stabilized and geotextile separation–drainage system improved the structural asset management test results from a completely failed road structure to primary plus load-carrying capacity. This research also demonstrated an improved correlation between the mechanistic material constitutive properties of the stabilized aggregate to the end-product field structural assessment relative to conventional California bearing ratio and unconfined compressive strength test results.

This paper presents the results of a laboratory study on the influence of grading and granular mineralogy sources (granitic gneiss, basalt and limestone) on the performance of treated and untreated granular materials used as surface pavements in unpaved roads. Results of bearing capacity, resilient modulus and compressive strength tests are discussed. Natural brine, calcium chloride, cement and a polymer emulsion treated samples were tested and compared to untreated samples. The combinations of product, mineralogy and grading showing great performance are finally pointed out.
