Paint additives are ingredients that improve the quality, performance, and functionality of paints and coatings. Paint additives modify the properties of paints to improve viscosity, reduce foam, control gloss, control flow, add anti-chipping ability, and enable paint to be more impact resistant to increase its effectiveness. Small amounts of paint additives are added to the coating formulation to ensure the paint's durability and enhance the finish of the coated film. The major end-user industries of paint additives are Architecture, Automotive, Industrial, and Wood and Furniture industries.

Polyester polymer concrete (PPC) was used in a trial application on a section of pavement that suffers from extensive studded tire wear. The purpose of the trial section is to determine if PPC is a possible repair strategy for this type of pavement damage. The PPC was applied in three methods; (1) as a 1 inch thick inlay of the entire lane that was diamond ground to remove all rutting from studded tire wear, (2) as an inlay of just the wheel paths that were diamond ground, and (3) as a feathered overlay of the existing pavement which had no diamond grinding to remove rutting. The test sections will be monitored for a minimum of five years to determine the performance of the PPC with particular emphasis on its ability to resist studded tire wear.

6月是建材行业的传统淡季，再加上基建和房地产投资增速双双回落等因素影响，水泥和平板玻璃整体需求较淡，水泥和平板玻璃产量环比均下降，重点联系企业水泥销量环比下降8.28%，而平板玻璃销量环比仅增长0.72%，主要是由于部分区域的经销商有囤货意愿所致。价格方面，水泥价格下跌，玻璃价格与上月基本持平。预计7月，建材行业仍将处于淡季，水泥和平板玻璃产销量将继续下滑，价格将持续下行。

2014年上半年，微刺激政策逐步发力，经济下行趋势缓解，但中国经济仍然面临需求疲软等问题。供求方面，全国固定资产投资增速止跌企稳，但房地产市场依然低迷，对建筑业需求影响较大，建筑业总产值和总收入增速继续回落；投资方面，建筑业固定资产投资增速回暖势头明显，同比上涨15.8%，比上年同期提高20.7个百分点；成本方面，建筑材料工业生产者价格指数为100.42，环比下降0.3个百分点，建筑业压力成本小幅度减轻。伴随着“楼市崩盘论”，新型城镇化、中西部地区投资环境的改善、自贸区的扩容、丝绸之路基础建设的逐渐落地，或将成为建筑业应对楼市疲软的机遇，建议投资者密切关注以上领域的投资机会。

进入4月，建材行业本该逐步进入传统旺季，但今年从水泥和平板玻璃市场表现来看，受房地产资金面紧张和中下旬部分地区遭遇雨水天气等因素影响，整体需求偏弱，不温不火。水泥和平板玻璃表现仍有差异：由于水泥供给得到改善，水泥价格上升；而玻璃产能释放较大，玻璃价格持续下跌。1季度，建材行业运行质量改善，行业盈利能力提高，实现利润总额690.93亿元，同比增长26.69%，增速较上年同期提高9.47个百分点，较上年末提高7.55个百分点。预计5月，受部分地区高温、雨水等天气影响，建材行业将逐步进入淡季，水泥和平板玻璃产销量将下降，价格将进入下行通道。

One serious problem reinforced concrete bridge decks face throughout the United States is the development of several cracks. Concrete bridge decks of all ages and sizes, some even constructed within the last several years, show different levels of cracking. Regardless of the type of superstructure, the number and length of spans, and the type of concrete used, cracks inevitably develop in every reinforced concrete bridge deck. There is a need to study the extent of cracking developed in concrete bridge decks so that the causes of cracking can be identified and counter measures established to minimize cracking in future bridge deck constructions. Cracks are critical on bridge decks because cracks provide access to harmful, corrosive chemicals that deteriorate the reinforcing steel, which is embedded within the concrete. Once chloride and other deteriorating agents penetrate concrete and make contact with the reinforcing steel, the deteriorating agents will corrode the steel, cause spalling, and eventually cause a loss of cross sectional area for the reinforcing steel. Such deterioration can affect the shear and moment capacity of reinforced concrete bridge decks. Also, the bridge deck cracks allow water and deicing salts to leak down through the bridge deck and damage the substructure and affect the aesthetics of the bridge.

This research investigates the behavior of a geosynthetic reinforced sandy soil foundation using laboratory model footing tests. The model footings were steel plates with dimensions of 152 mm × 152 mm. The parameters investigated in this study included top layer spacing, number of reinforcement layers, vertical spacing between layers, tensile modulus and type of reinforcement, and embedment depth. The test results showed that the inclusion of reinforcement can appreciably improve the soil's bearing capacity. Higher tensile modulus geosynthetics performed better than others; and that sand reinforced by the composite of geogrid and geotextile performed better than those reinforced by geogrid or geotextile alone. The test results also showed that the reinforcement configuration/layout has a very significant effect on the bearing capacity of reinforced foundation. The results of the model footing tests were compared with the analytical solution developed by the authors in a previous study. The analytical solution gave a good predication of the experimental results of footing on geosynthetic reinforced sand.

Spiralnails are hollow steel pipes extruded and twisted to form a square helical shape. They are driven rather than drilled, and thus they do not require cement grout to develop a bond with the soil, and provide immediate internal stability improvement to a soil mass. Because effective and economical designs require an improved understanding of individual and group spiralnail behavior, a 6-m (20-ft) tall, top-down vertical excavation was constructed using spiralnails in a well-characterized, engineered fill. The spiralnail reinforcement design used existing soil nail design methods to achieve an acceptable factor of safety using nail lengths and spacing comparable to those common for a conventional grouted nail design. The objective of the project was to measure the performance of the spiralnail reinforced soil mass in order to evaluate the applicability of existing soil nail design methods to spiralnail design. The paper describes the design, construction, soil characterization and properties, instrumentation, and presents the measured load-displacement behavior of the spiralnails and observed deformation of the reinforced soil mass. A preliminary analysis of load-displacement data is presented, and calculated spiralnail equivalent bond stress values are provided. Based on the measured deformations and using an empirical correlation, the spiralnail-reinforced soil mass performance is compared to a grouted nail-reinforced soil mass.
