TL;DR: In this article, surface area specific runoff coefficients were measured for nonclogged Portland cement pervious concrete systems according to the rational method and the results obtained are important for the design of perviouscrete runoff management systems.
Abstract: Surface area specific runoff coefficients were measured for nonclogged Portland cement pervious concrete systems according to the rational method. The systems were simulated with pervious concrete blocks with porosities ranging from 16 to 27% placed over sand subbases. Rainfall was simulated in a flume setup with surface slopes ranging from 2 to 10%. There was negligible runoff for typical rainfall events under 100 years frequency in South Carolina. Runoff rates were also simulated for a combination of direct rainfall and additional stormwater runoff from adjacent areas. The results obtained are important for the design of pervious concrete runoff management systems.

TL;DR: In this paper, the feasibility of using MICP bio-grouting to improve the mechanical response of pervious concrete piles under axial pull-out loading was evaluated, and two instrumented concrete piles (test units) were subjected to pullout loading at the Soil-Structure Interaction Facility at Lehigh University.
Abstract: Bio-grouting is an environmentallly friendly, sustainable, and low-cost ground improvement technique, which mainly utilizes microbial-induced carbonate precipitation. Previous large-scale applications of MICP have encountered practical difficulties including bio-clogging, which resulted in a limited zone of cemented soil around injection points. The research presented in this paper focuses on evaluating the feasibility of cementing a limited soil zone surrounding permeable piles using MICP bio-grouting to improve the mechanical response of permeable piles under axial pull-out loading. Two instrumented pervious concrete piles (test units), one with and one without MICP bio-grouting, were subjected to pull-out loading at the Soil-Structure Interaction Facility at Lehigh University. The pervious concrete pile served as an injection point during the MICP bio-grouting. The mechanical responses of the test units and surrounding soil were analyzed, along with shear wave (S-wave) velocities, moisture, and CaCO3 c...

TL;DR: In this paper, the shrinkage of porous concrete was investigated and the main influence was exerted by CO2, and only in the second place by the humidity of the environment, and the lowest compressive strengths were obtained after 30 days storage in 30 and 10% CO2.

TL;DR: In this article, the authors present the results of Part 1, Task 2 of the ISU-FHWA project entitled "Concrete Pavement Surface Characteristics Project." It addresses the noise issue by evaluating conventional and innovative concrete pavement noise reduction methods.
Abstract: This document contains the results of Part 1, Task 2 of the ISU-FHWA project entitled "Concrete Pavement Surface Characteristics Project." It addresses the noise issue by evaluating conventional and innovative concrete pavement noise reduction methods. The first objective of this task was to determine what if any concrete surface textures currently constructed in the United States or Europe were considered quiet, had long-term friction characteristics, could be consistently built, and were cost effective. Any specifications of such concrete textures would be included in this report. The second objective was to determine whether any promising new concrete pavement surfaces to control tire-pavement noise and friction were in the development stage and, if so, what further research was necessary. The final objective was to identify measurement techniques used in the evaluation. The Part 1, Task 2 evaluation reported herein included (1) examination of conventional concrete pavement noise reduction methods used in the United States; (2) identification of promising new concrete pavement surfaces to control tire-pavement noise and friction in Europe; and (3) initial consistent field measurements of tire-pavement noise and friction with respect to texture. The evaluation concludes that (a) careful construction practices in the United States for artificial turf and burlap drag, longitudinal tining, and diamond grinding can be used to initially control noise (99/100-104/105 dBA) and provide adequate initial friction; (b) the noisiest pavements (>104/105 dBA) should be rehabilitated immediately, with no new noisy pavements constructed; (c) to achieve the quietest concrete pavements (<99/100 dBA), innovative solutions such as exposed aggregate and pervious concrete, need to be advanced; and (d) more study is necessary to understand the change of noise and texture characteristics over time and to increase consistency.
