Impacts of opening baffle of city road tunnels on natural ventilation performance

Weixiao YANG, Jincheng XING, Jianxing LI, Jihong LING, Haixian HAO, Zhiqiang YAN

Frontiers of Structural and Civil Engineering 2013, Volume 7, Issue 1,   Pages 55-61 doi: 10.1007/s11709-013-0194-x

Abstract: Based on the opening baffle mode for natural ventilation of city road tunnels, this paper studies theperformance, the paper reached the conclusions as follows: 1) When installation angle is larger than 45° and tunnelThe baffle reaches its optimal performance when the length of the baffle is equal to the width of the cityroad tunnels. 3) Baffle exhaust could increase by 30% when it is installed in the downstream of openings

New Mode of City Without Road Congestion—Saving 70% of Land, Capital and Energy

Dong Guoliang

Strategic Study of CAE 2006, Volume 8, Issue 1,   Pages 11-17

Abstract:

This paper puts forward “Ideas on Reforming City Gene” and “New Smooth City ModeAt present, city suffers from fatal gene —“misplaced space”，which leads to ten seriousproblems hindering city sustainable development： occupation of too much city land, low efficiency, highIt is better to carry out study from perspective of 4 levels of “city transportation—citypeople respectively, thus constructing a “New Smooth City Mode”.

Development and road performance of clear asphalt with high transparency and adhesion

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 2,   Pages 238-255 doi: 10.1007/s11709-022-0898-x

Abstract: Clear asphalt (CA) currently used in light-colored asphalt mixtures (LCAM) exhibits poor transparency and adhesion. Therefore, a highly transparent CA (HCA) modified using a silane coupling agent (KH550) was prepared. Furthermore, LCAM was prepared by mixing CA and limestone aggregates. The properties of the HCA and ordinary CA (OCA) were characterized using conventional asphalt tests, optical tests, pull-off tests, ultraviolet aging tests, dynamic shear rheometry, Fourier-transform infrared spectroscopy, differential scanning calorimetry, and scanning electron microscopy. Whereas Marshall, moisture resistance, wheel tracking, trabecular bending, and British pendulum tests were employed for the LCAM. The transmittance and spectral reflectance of the HCA were 123.30 and 3.74 times greater than those of the OCA, respectively. The complex modulus and viscosity-aging index of the HCA were 48% and 53% less than those of the OCA, respectively. After modification with KH550, the Marshall stability ratio, tensile strength ratio, and flexural strain of the HCA-prepared LCAM increased by 12.92%, 25.06%, and 23.90%, respectively. However, the rutting resistance of the HCA-prepared LCAM was 14.3% less than that of the OCA-prepared LCAM. The comprehensive performances of the HCA and HCA-prepared LCAM were 49.2% and 10.3% greater than those of the OCA and OCA-prepared LCAM, respectively, indicating a high application value in the future.
