After analysis status past decades, a novel technology system eco-friendly pavements proposed considering two solutions, materials modification structure improvement....

Abstract Several data processing techniques (DPTs) have been implemented for evaluating pavement surface texture to partially replace onsite inspections by humans. However, the extensively varying real‐world situations resulted in challenges widespread adoption of DPTs. To overcome these challenges, we propose use a convolutional neural network (CNN) calculate mean depth (MTD) without computing feature statistics. Because CNN is capable automatically learning features, proposed method does...

Pavement heats the near-surface air and affects thermal comfort of human body in hot summer. Because a large amount connected porosity porous Portland cement concrete (PPCC), parameters PPCC are much different from those traditional (PCC). The temperature change characteristics effects on surrounding environment also different. A continuous 48-hour log PCC five kinds with were recorded open temperatures at heights above specimens tested using self-made enclosed boxes to analyze temperature....

Portland cement hydration is related to mechanical properties, durability and sustainability of concretes, also the service level building structures. This paper will report an initial understanding under low temperatures based on several laboratorial investigations (e.g. thermal gravity analysis /derivative thermogravimetry X-ray diffraction). Mechanical behaviours phase evolution are discussed in this report. Calculation Powers' model was utilised analyse process temperatures. Research...

The waste clay bricks from debris of buildings were evaluated through lab tests as environmental friendly materials for pavement sub-base in the research. Five sets coarse aggregates which contained 0, 25%, 50%, 75% and 100% crushed bricks, respectively, blended with sand treated by 5% cement. test results indicated that cement aggregate contains brick had a lower maximum dry density (MDD) higher optimum moisture content (OMC). Moreover, unconfined compressive strength (UCS), resilience...

The vertical integration of ‘Generation-Grid-Load-Storage’ in microgrids for port areas is a prevailing trend.

Sufficient pavement skid resistance is one of the essential factors to ensure traffic safety. The real contact area (Ar) between tire and road significant for understanding improving performance. In this study, tire–road measured by squeezing a smooth underside-dyed rubber block into specimens, using self-designed fixture mounted on universal test machine. three-dimensional (3D) printing technology used separate specimens with multi-scale roughness.

Three-dimensional (3D) parameters are being increasingly used to characterise the pavement macrotexture. This study explores influence of evaluation area and sampling interval on 3D macrotexture parameters. The point clouds surfaces with different morphologies captured by a scanner, is divided into non-overlapping rectangular areas sizes. original diluted obtain data intervals. concerned include root-mean-square surface height Sq, slope Sdq, peak density Spd, arithmetic mean principal...

This study investigates the establishment and calibration method of rut depth (RD) prediction model inverted asphalt pavements (IAPs), based on full-scale accelerated pavement testing (APT), which facilitates accurate reliable design or maintenance IAPs. A power function is adopted for construction progression before failure stage, typical permanent deformation curve flexible pavements. The APT loading history divided into units, according to difference in physical conditions, providing...

Maintaining good friction performance of highway pavement is important for road safety. The affected by many factors, and the present study investigates effect compactness on texture asphalt concrete during polishing process. Two three-dimensional (3D) parameters mean depth (MTD) were used to characterize surface AC-13 concrete. differences are then being analyzed among in field, rutting slabs with 97% (RS-97), 100% (RS-100), 103% (RS-103). polished a circular vehicle simulator (CVS). 3D...

The asphalt pavement texture is vertical asymmetric, and the tread rubber may contact part of surface. Therefore, penetration depth (d) probably essential for developing a reliable relationship between performance texture. This study investigated effect on d, simplified by squeezing plate into three-dimensional (3D)-printing specimens. 44 specimens were manufactured based surface morphologies pavements artificial surfaces with characteristics specimens' characterised parameters from...

Water reducing agents (WRAs) are usually utilized in cement concretes to reduce the water-cement ration, increasing mechanical strength and improving durability of concrete structures. As a kind widely used construction materials pavement structures, i.e., base or subbase course, stabilized aggregates (CSAs) have face their own problems, e.g., drying shrinkage at early ages. To evaluate feasibility water agent aggregates, its effects on engineering performance, six groups were prepared...

The structure design and mechanistic calculation of inverted asphalt pavements are mainly based on linear layer elastic theory with the assumption that cement-treated subbase (CTB) is complete without cracks. This study investigates optimal combination for according to calculated critical responses considering cracks in CTB layer.
