Evaluation of Seasonal Effects on Subgrade Soils

Transportation Research Record: Journal of the Transportation Research Board, 2003
One objective of the FHWA’s Long-Term Pavement Performance (LTPP) program is to determine climatic effects on pavement performance. The LTPP instrumentation program includes seasonal monitoring program (SMP) instrumentation to monitor the seasonal variations of moisture, temperature, and frost penetration.

Soil Moisture as a Factor in Subgrade Evaluation

Transportation Engineering Journal of ASCE, 1977
The pretesting treatment is for the purpose of providing soil specimens having moisture conditions similar to those under the pavements. This is a necessary step in the laboratory evaluation of subgrade soils because soil moisture is an important factor affecting the supporting power of the subgrade.

Study on the Health Monitoring Technology of Saline Soil Subgrade and the Distribution Law of Subgrade Water Temperature

2020 IEEE 5th International Conference on Intelligent Transportation Engineering (ICITE), 2020
In order to explore the mechanism of salinized soil disease, the real subgrade in Hexi area, Gansu Province, China was selected and the health monitoring system of salinized soil subgrade was established. The response effect of the test system was good.

Impact of subgrade soils on pavement roughness

Canadian Geotechnical Journal, 2016
To highlight the impact of subgrade soil variability on the pseudo-profile and roughness at the end of road construction, a research program has been carried out at the Laboratoire sur les chaussées et matériaux bitumineux at École de technologie supérieure (ÉTS).

Horizontal Subgrade Modulus of Granular Soils

1984
Although the horizontal subgrade modulus plays a significant role in problems dealing with lateral-load carrying capacity of piles, a rather wide range of values is available in literature depending upon the equation, chart, or table used to obtain the modulus. This task is further complicated on account of lack of uniformity of definitions used.
