“…For example, regular testing of subgrade would provide a more robust evaluation of the seasonal variations of its parameters. When such testing is accompanied with, for example, the data concerning the pavement courses [15] and deflection measurements and analysis [16] it can lead to obtaining more accurate methods for predicting the service life of road pavements.…”

The subject matter of this paper is assessment of the suitability of a dynamic cone penetrometer for determination of the state of soil. The principle of operation of the dynamic cone penetrometer, similar to commonly used DPL penetrometers, is described in the paper. Next the results of investigation conducted in Poland using a new dynamic cone penetrometer are presented. A series of measurements were performed in real field conditions. An attempt was made to correlate the results obtained with the dynamic and static cone penetrometers (CPT) respectively. These correlations were then subjected to validation to obtain a preliminary evaluation of the suitability of the dynamic cone penetrometer for determining the state of soil.

“…Pavement layer temperature and moisture predictions are calculated on an hourly basis and used to estimate the material properties for the foundation and pavement layers throughout the design life [15,27]. It was shown that seasonal temperature variations carry out a considerable drop in pavement durability and significantly affect the overall performance of the pavement system, which is greatly affected by temperature and moisture [8,28]. An increase in moisture content reduces the load-carrying ability of subgrade soils.…”

“…Therefore, the climates of the study regions were matched with weather stations in the US. This approach has been used by many researchers implementing AASHTOWare outside the US [8,14,18,28,36]. For this purpose, annual average data for minimum winter and maximum summer temperatures, spring and autumn temperatures, average temperature, average precipitation, elevation, wind, and solar radiation were collected for three study regions and matched with the US weather stations as shown in Table 4 and Figure 3.…”

“…and, as well as predicted performance for the entire service life of the pavement. This software computes the stresses, strains, and deflections through the life of the pavement and estimates the distresses with the help of distress transfer functions [5]; and it gained popularity in European countries such as Italy [6], Poland [7,8], Romania [9].…”

The economic growth in developing countries triggers investments in highway networks. Thus, this requires a re-evaluation of existing design practices, which are mostly empirical. An alternative is the relatively recently developed Mechanistic-Empirical (M-E) design method. It has major data challenges and must be identified before a major switch. In this study, three different climatic regions for Turkey were analyzed optimizing 162 design combinations. Results showed that climate, traffic, and reliability parameters extremely affect the performance of the pavement. As in the current practice of Turkey, climate and material effects are not currently considered; these should be further studied considering the local calibration steps.

“…As a result, a response regarding pavement structure for the base foundation was obtained, serving as a design reference [68]. Also, a comparison of the season-dependent equal temperature to the effect of seasonal temperature changes on the fatigue strength of flexible and semi-rigid pavement systems of flexible and semi-rigid pavement systems at the yearly equivalent temperature of 10℃was performed [69]. The strain and stress states were obtained using the ANSYS mechanical tool.…”

Transport and international agencies invest millions of dollars on road projects to support countries develop their infrastructure; therefore, it is important to ensure longer service life and value for money. The primary function of the pavement structure is to keep distresses, including fatigue cracking and permanent deformation, to an acceptable limit so that the pavement can withstand applied vehicle load and repetitions during the service duration. Furthermore, the layered structure of the pavement is intended to ensure that the vehicle contact pressure is distributed in such a way that critical responses at the bottom layer of the pavement are low enough to avoid severe damage. Two typical procedures associated with roadway pavement design are empirical-based and structural analysis methods. However, the empirical-based methods have significant shortcomings, as predicting the mode and extent of pavement performance becomes a major challenge. Alternatively, the structural analysis methods have advanced extensively with computers since they consider crucial factors such as traffic loads, material characteristics and environmental conditions. The imputation of these parameters into the computer algorithm contributes to a better understanding of the mechanical performance of constituent pavement material responses. The predicted responses enable highway engineers to select appropriate pavement compositions that will deteriorate at a satisfactory level during the time of service. The most common structural analysis approaches are analytical modelling and numerical simulation. On the other hand, differences in analysis results generation using these approaches have been a notable concern. This review article presents a synopsis of typical pavement design methods and the problem connected with them; structural approaches to identify factors influencing their accuracy. Furthermore, computer algorithms use due to their usefulness, and the assumptions of layered theories employed in pavement structural design are discussed to uncover potential drawbacks for future upgrades.
