“…In this analysis, a distinction was made between sensors embedded into the pavement [46][47][48][49][50][51][52] and those applied directly on the pavement surface [42][43][44]. These monitoring systems focus either on the monitoring of the propagation of concealed cracks [42,43,46,48], or on the estimation of structural capacity [47,[49][50][51][52]57] influenced by pavement parameters that can be measured by specific sensors, such as strain, temperature, or moisture gauges. Nevertheless, embedded methods are not exclusive to the monitoring of structural condition, as these systems have also been used to monitor functional aspects.…”

Nowadays, pavement management systems (PMS) are mainly based on monitoring processes that have been established for a long time, and strongly depend on acquired experience. However, with the emergence of smart technologies, such as internet of things and artificial intelligence, PMS could be improved by applying these new smart technologies to their decision support systems, not just by updating their data collection methodologies, but also their data analysis tools. The application of these smart technologies to the field of pavement monitoring and condition evaluation will undoubtedly contribute to more efficient, less costly, safer, and environmentally friendly methodologies. Thus, the main drive of the present work is to provide insight for the development of future decision support systems for smart pavement management by conducting a systematic literature review of the developed works that apply smart technologies to this field. The conclusions drawn from the analysis allowed for the identification of a series of future direction recommendations for researchers. In fact, future PMS should tend to be capable of collecting and analyzing data at different levels, both externally at the surface or inside the pavement, as well as to detect and predict all types of functional and structural flaws and defects.

The main objective of this study was to investigate the effect of SBS polymer and warm mix additive on the performance of bituminous concrete mixes. SBS polymer dosage was kept 3%, 5% and 7% and Zycotherm additive dosage was kept 0.1% for all binder mixes. Comparisons were made between Base bitumen, SBS modified bitumen and Zycotherm modified bitumen. For preparation of bituminous mixes, two different types of aggregates were used in this study i.e. Limestone and riverbed aggregate. To evaluate the performance of modified binder; Marshall Stability test, Indirect Tensile Strength (ITS) test and Rheological test were performed on binders and bituminous concrete mixes. From Marshall Stability test, SBS dosage of 5% was found to be optimum polymer content for both aggregate mixes. Maximum tensile strength for both the aggregate bituminous mixes was achieved at 5% SBS content. It was observed that maximum Marshall Stability was achieved when Limestone aggregates were used for preparation of bituminous mixes. Zycotherm additive does not have any significant effect on the properties of bituminous concrete mixes. However Zycotherm additive tends to decrease viscosity of binder at a temperature above 100 ˚C which will result in lower mixing temperature without compromising the performance of bituminous binder. Rheological test on different binders has shown that Zycotherm additive has very less affect on rutting resistance of modified bitumen. It was finally concluded that best results were obtained from Limestone aggregates using 5% of SBS polymer and Zycotherm additive has no significant effect on mechanical properties of mix

This study examines the influence of the water to cement ratio (w/c) on the critical degree of saturation (DOSCR) of cement paste samples using length change measurements. Length change was measured using thermomechanical analysis (TMA) for cement paste samples with different degrees of saturation (DOS), ranging from 100% DOS to 0% DOS. The damage induced by a freezing and thawing cycle (FT cycle) was deduced from length change measurements. The results obtained from length change measurements were correlated with the amount of freezable water obtained from low-temperature differential scanning calorimeter (LT-DSC) tests. It was observed that samples with a DOS greater than DOSCR exhibited damage while those with a DOS less than DOSCR did not show damage. It was concluded that the DOSCR slightly increases when the w/c increases from 0.35 to 0.45. However, there was not a significant increase in DOSCR when the w/c increases from 0.45 to 0.55. However, it should be noted that freeze-thaw performance is dependent on w/c. Indeed, permeability of cementitious materials and the amount of freezable water are directly dependent on the w/c and directly affect the freeze-thaw performance of concrete.
