“…Otherwise, water would accumulate onto the low permeability layer and keep the upper layer wet; freezing of the accumulated water might then unbind the upper layer. Water would decrease the AC pavement bearing capacity and service life [17,18].…”

Influence of Temperature and Moisture Content on Pavement Bearing Capacity with Improved Subgrade

et al. 2019

Environmental conditions (temperature, moisture and the intensity of the sun) influence variation in asphalt pavement strength during the year. Lithuania is situated in a zone by average warm summers and average cold winters, and the most important climatic factor is the variation of the air temperature. This study presents the influence of temperature (of asphalt concrete (AC) and subgrade layers) and moisture content (of subgrade layers) to the pavement bearing capacity. The experimental research was obtained in five pavement sections of the experimental road. This experimental road was constructed in 2007 in Lithuania and is operated for more than 12 years. This paper presents a statistical analysis between the bearing capacity and the thickness of the asphalt concrete layers, the temperature and moisture content of different pavement layers, among sections, loaded and unloaded lanes (right and left wheel paths and tracks). The bearing capacity was evaluated by a falling weight deflectometer (FWD), temperature and moisture content by electronic sensors and thickness of AC layers by Georadar. Analysis of overall E0 and E0,h9 (bearing capacity at a depth of 9 cm from asphalt surface) data declares that seasonal impact on pavement structural strength due to a change of subgrade bearing capacity remains after correction of asphalt stiffness dependent on the temperature in the layer. However, it was detected that neither E0 nor E0,h9 are related to moisture content at a depths of 100 cm, 130 cm and 150 cm.

“…There is some evidence to suggest that water has less impact on the ticker and well-constructed pavements than it does on thinner ones [19]. It appears that in thicker pavements, the effect of water may be more indirect than in thinner ones, reducing material stiffness leading to later distress [17].…”

“…The moisture content of unbound granular (UBG) pavement materials has a significant influence on their structural performance (Charlier et al . ; Saevarsdottir and Erlingsson ). Non‐destructive techniques for measuring moisture within these materials are therefore of interest for a variety of pavement investigation and monitoring applications.…”

This paper reports on a laboratory experiment comparing permittivity measurements using a modified free-space approach to results using common-offset ground-penetrating radar and time-domain reflectometry on moist and compacted samples of unbound granular road pavement materials. In the first part of the experiment, unbound granular samples from the same source were prepared to varying moisture contents and a fixed target density. Separate samples were prepared for modified free-space and time-domain reflectometry testing, all of which were also measured using ground-penetrating radar. In the second part of the experiment, samples were mixed to a consistent gravimetric moisture content and varying densities before undertaking the modified free-space, time-domain reflectometry, and ground-penetrating radar measurements. Reasonably good agreement was found between modified free-space and ground-penetrating radar measurements, which also compared well with literature relations for crushed rock pavement materials. The time-domain reflectometry results were relatively consistent with those literature relations, although they appeared to deviate from the ground-penetrating radar and trend of modified free-space results for lower density and drier samples.

“…However, unbound granular pavements with thin bituminous layers are highly susceptible to premature failure if there is moisture infiltration into the base or subgrade . Ingression of moisture in the pavement through shoulder or surface results to increased pore water pressure or decreased matric suction leading to reduced effective stress, strength and stiffness (Charlier et al 2009). Moreover, in pavement engineering, the existence of excess moisture in unbound pavement materials, particularly when combined with heavy traffic load leads to enhanced pavement weakening and decrease in service life (ARA, 2004;Erlingssson, 2010).…”
