Thermal Actions on the Materials During Deck and Pavement Construction

Abstract

The article presents the results of the research on thermal actions on the materials occurring in the cross section along the depth of the bridge deck and bituminous pavement during its construction. The impulse to curried out the research was the need to explain the causes of the blistering of bituminous waterproofing membranes and asphalt pavements often observed on the bridge decks. The paper presents the examples of such failures and the analyses of possible mechanisms of the phenomenon. Research indicates a significant influence of all technological processes on the temperature of materials in the cross section as well as daily temperature changes. The probability of initiation of reactions between concrete components with gaseous products has been confirmed in such conditions. The susceptibility of bituminous materials to gas emission and blistering is the subject of a separate study. The research was part of a research project carried out under the contract INNOTECHK3/IN3/50/229332 /NCBR /14 [13].

Causes of Asphalt Pavement Blistering: A Review

“…Indeed, blisters can reach a stable state, break, or lead to delamination, depending on the mechanical and adhesion properties of the materials [8,9]. The uplifts have a circular shape with extremely variable dimensions: their diameter can reach 1 m, and their maximum elevation is usually a few centimeters over the ideal and initial flat surface [10]. It often affects asphalt mixtures on asphalt roof shingles [11], pipelines [12], pipes for drinking water supply [13], Portland cement concrete bridge decks [14,15], steel deck bridge pavements [16], dams [7], pumped-storage power stations [7], runways [17], sidewalks [18], carriageways [5], waterproofing membranes [19], and asphalt-covered concrete structures [20] in south-and west-facing areas.…”

“…According to the scientific literature, blistering is an asphalt distress phenomenon whose origin and development mechanisms still need investigation due to its low frequency compared to fatigue and rutting. Blistering consists of local uplifts that are essentially circular with variable dimensions: their diameter can reach 1 m, and their maximum height is usually a few centimeters above the ideal and initial flat surface [10]. It is an irreversible (or partially reversible) process consisting of non-linear blister growth dynamics, which can start during daytime hours at the interface between two layers or within the upper layer and can have different consequences [7].…”

“…A direct result of exothermic hydration reaction and the hardening of cement binder is a rapid increase in temperature in the concrete mass [1][2][3][4][5][6][7][8]. Temperature development in structures is determined by two opposing phenomena heat emission as a result of the exothermic process of cement hydration and heat exchange between the structure and its surroundings.…”
