“…The one-dimensional transient moisture permeation (transient moisture permeation) apparatus is a device newly developed in our laboratory in Hokkaido University, Sapporo, Japan and manufactured for this study to measure the moisture by the weight changes (±0.1g) of samples under respiratory action of concrete structures and asphalt pavements. In this test, a KCL-1000 apparatus (Tokyo Rika Co. Ltd.,) was used [ 6 ]. (I. Sasaki, Journal of the Japan Petroleum Institute 49 (1) (2006) 33–37 [ 6 ]).…”

In concrete structures (concrete), damage from cracks, deterioration, amorphization, and delamination occur in some structures, causing disaggregation (concrete changed to very fine particles) and hollowing out of the concrete. In concrete pavements, damage from large amounts of pop-out of aggregate occurs from the surface of the concrete pavement 4–5 hours after spraying of snow melting agent on the surface of the pavement. The damage from disaggregation, blistering, cracks, and peeling-off of a surface course have also been observed in asphalt runways and highways. The damage from disaggregation, cracks and pop-out of aggregate in asphalt pavements and concrete structures have long been seen as strange and unexpected and have defied explanation. As a result of examinations in various experiments, it was concluded that all of the unexplained kinds of damage of both asphalt pavements and concrete structures were caused by Trace Quantities of Organic Matter (TQOM), Air Entrained (AE) water reducing agent in air and/or cement, and surfactant in snow melting agent. The emission sources of TQOM and these organic substances were also identified by chemical analysis for these unexpected and unexplained phenomena. The TQOM includes phthalate compounds (phthalates in the following), amine compounds, phosphate compounds, snow melting agent and Sodium Polyoxyethylene Nonyl phenyl Ether Sulfate (SPNES). SPNES is a surfactant in windshield washer fluid for automobiles. We found that the water content and content of organic matter in damaged asphalt pavements and concrete structures are also important indicators for the damage. Further, a new evaluation method for amorphization was proposed in this study and it appears suitable for evaluating the safety of concrete structures along roads which were exposed to TQOM in severely air-polluted environments.

“…However, the influence of the physical state of water in the diffusion measurements has yet to be analyzed in more detail. Some studies have considered water in the liquid state (Cheng et al 2003;Kassem et al 2006;Nguyen et al 2005;Wei 2009); others controlled the relative humidity of the environment in contact with the sample to simulate water in the vapor or molecular form (Arambula et al 2010;Kringos et al 2008;Sasaki et al 2006).…”

“…However, the authors previously found that the cause of water accumulation in pavement mixtures is water vapor permeation and condensation, and developed a new test method to simulate mass transfer in a transitional cyclic environment 4) . The moisture permeation test suggested that moisture vapor in the air permeates easily into the bituminous pavement layers and accumulates, even though the surface course is practically impermeable to liquid water.…”

“…Although the authors previously proposed the fundamental mechanism of water accumulation as vapor permeation and condensation under specifi c transitional moisture conditions, the approach was only oneday simulation and for fresh water vapor as a transfer fl uid 4) . This study investigated the following two issues involved in mass transfer in a bituminous pavement and concrete deck slab.…”

Water-related damage is one of the major problems for the durability of the bituminous pavement and concrete slabs of concrete deck bridges. In particular, damage can be drastically accelerated by the intervention of water and some chemicals such as surfactants and salts. Therefore, the mass transfer mechanism of water and the mechanism of chemical absorption in pavement materials are important to study. The authors previously pointed out that water storage in bituminous pavement layers is caused by moisture vapor in the air, and developed a new moisture permeation test apparatus to analyze the mass transfer. Based on this test method, the present study showed experimentally that water and surfactant accumulate in the bridge deck pavement and concrete slabs. Water accumulation in the pavement and deck slabs increases according to the daily climatic fluctuation. The repetitive moisture permeation test showed that alkylphenol-ethoxylate type surfactant applied on the top surface permeates through water-impermeable pavement layers and accumulates in the concrete slab
