This paper documents the effectiveness of a recycle-in-place (Remixer) process on US175, using results from GPR, FWD, PSPA, condition surveys (crack mapping) and laboratory testing. FWD and PSPA results indicate that the remixed sections are stiff, and the deflection values are in the range typically observed in the Interstate Highway system. This recycling process removes 38mm of AC and adds 2...

The concept of rational pavement design for design of bituminous pavement was conceived during the 1960s (Dorman 1962, Monismith et al. 1961). Its upgraded version is known as Mechanistic-Empirical (M-E) pavement design, and is at present popularly being used for design of bituminous pavements in various countries. A number of pavement design guidelines (Austroads 2004, French 1997, IRC:37 2001...

This paper aims to explore and evaluate aerial imagery deep learning technology in pavement condition evaluation. A convolutional neural network (CNN) model, named PCIer, was designed process images produce index (PCI) estimations, which are classified into four scales of Good (PCI ≥ 70), Fair (50 ≤ PCI < Poor (25 50), Very 25). In the experiment, datasets were retrieved from published repor...

Çalışmada üstyapı performans göstergesi olarak kullanılan Üstyapı Durum İndeksi (PCI) ve yolcu otomobilinde maruz kalınan tüm vücut titreşimi miktarı arasındaki ilişkilerin matematik modellenmesi amaçlanmıştır. Titreşim ölçümleri, teknik detayları ISO 2631 standardında açıklanan frekans ağırlıklı veri işleme yöntemine göre analiz edilerek düşey doğrultuda aw değerleri elde edilmiştir. Bitümlü s...

resilient modulus of pavement materials is a key property required for the pavement thickness design. this paper describes the results of an experimental study on the effects of temperature and loading frequency on the resilient modulus of a sbs polymer modified asphalt concrete under dry and saturated conditions. dynamic creep tests were conducted on dry and saturated specimens of the mixture ...
