This paper presents the results of laboratory research on asphalt mixtures containing reclaimed pavement (RAP) and shingle, including study their linear viscoelastic (LVE) behaviour fatigue characteristics. Complex modulus measurements using tension-compression test cylindrical specimens were conducted to determine LVE behaviour. Sinusoidal cyclic loadings with a strain amplitude approximately 50×10−6 applied at several temperatures (from−30°C to+40°C) frequencies (from 0.01 10 Hz). In...
In this paper, a possible way to capture the combined effect of oxidative ageing and moisture damage on mixture performance has been proposed. The formulations that are needed for finite element (FE) modelling oxygen diffusion process have established. proposed model should be able link in-time changes mastic as function morphology, propensity properties physical asphalt due loss adhesive and/or cohesive bonding. Such an FE can help find trends relationships assist in development predictive...
Freeze–thaw action is considered to be one of the most destructive actions that can induce significant damage in stabilized subgrades seasonally frozen loess areas. Laboratory tests including frost heave – thaw shrinkage and microstructure change during freeze–thaw cycles were conducted evaluate volume rate with cement, lime, fly ash under impact cyclic conditions. The specimens collapsed after eight (192 h), but had no visible all completed. All samples underwent a much smaller than alone...
In this paper, the combined effect of aging temperatures and cooling medium on rheological properties asphalt binder was experimentally investigated evaluated. Two 70/100 penetration grade binders, which were part core materials used by active RILEM committee CMB-252, selected for purpose. The artificially aged to six different conditions, first with Rolling Thin Film Oven Test (RTFOT) at three (123°C, 143°C, 163°C), then, standard Pressure Aging Vessel (PAV). Next, temperature frequency...
ABSTRACT This paper presents the results of an experimental campaign fatigue tests carried on several asphalt concrete mixes. The main goal this study is to evaluate effect binder characteristics resistance intrinsic damage approach developed at "Département Génie Civil et Bâtiment" (DGCB) used determine rate per loading cycle. confirm efficiency mixes and quantify changing some mix resistance. briefly presented are analyzed compared.
Modifying asphalt binders is an effective method of improving the performance pavement, such as its resistance to rutting. However, because modification changes behaviour binders, substantial laboratory testing required before field application determine best mixtures. This research aimed evaluate impacts temperature, stresses, polymer type, and rate on rutting binder modified with fly-ash-based geopolymer (GF), styrene butadiene (SBS), a combination SBS GF. The rheological properties were...
Using geopolymer as a modifier for asphalt binders and mixtures gained momentum investigation in recent decades. Limited research investigations attempted to link the effect of temperature traffic loading on rheological properties performance geopolymer-modified binders. The primary objective this study is evaluate fly ash-based (GF), styrene-butadiene-styrene (SBS), combination GF with SBS at low intermediate temperatures. neat modified (4%GF, 8%GF,12%GF, 2%SBS, hybrid (2%SBS+8%GF)) were...
3D Concrete Printing (3DCP) technology is rapidly gaining popularity in the construction industry, particularly for transportation infrastructure such as bridges. Unlike traditional methods, this innovative approach eliminates need formwork and enhances both economic efficiency sustainability by lowering resource consumption waste generation associated with formwork. This paper examines current research on 3D-printed concrete bridges, highlighting key areas mixtures, design processes,...
