Recommendations included improving drainage, stabilizing poor subgrade soils, avoiding substandard materials, and implementing a strong quality assurance program.
A Study on Design and Analysis of Precast Box for Road Bridge Construction us...ijtsrd
Transportation always plays an important role in economic growth and globalization for a country. Road transportation is one of the main transporting way in India. Therefore it requires connectivity of cities. Hence bridges and culverts are constructing to connect Roads.Box Culvert can be defined as a structure having box shape which is constructed below the embankment to drain water from one side of the bank to the other side of the bank. Failure reasons of a Box Culverts are maintenance failure, erosion and increase in scour depth, and Installation Failures. To improve the problems occurring in the Structure are described briefly. Box Culverts are normally constructed without RCC cut off and curtain walls. Due to which structure gets damaged easily. In previous researches Box Culvert are constructed with PCC cut off and curtain walls while taking various parameters in design. Movements of people and transportation will not be affected because structure will not be constructed number of times because life of structure will be very long. Seepage pressure is less in box culvert with RCC Cut off and curtain walls because the gripping in RCC structure is good as compare to PCC Structure, and Seepage pressure is directly proportional to voids that makes PCC structure unstable against seepage pressure. BM of PCC walls is also less than as compare to RCC walls. Life of structure will also increase around two times, and also Government planning will not be affected because project will be for long time period. In designing of structure the two major factors should be kept in mind i.e. economy and safety. If the load is overestimated than the structure will be uneconomical whereas if the load is underestimated the safety of structure will be compromised. Hence the calculation of load and their combination should be done very precisely The study included estimation of PCC and RCC Cut off and Curtain walls through comparative results in SOR 2017.

This document discusses the disadvantages of using a blanket factor of safety approach when designing remedial measures for railway earthworks. It argues that seeking only to improve the factor of safety can lead to overly conservative and expensive remedial designs. Instead, it proposes a new approach where performance requirements of the track are the key design criteria, and remedial works specifically target the key causes of poor performance in a more cost-effective manner. An example project is described to illustrate how this new approach was applied.

GIS Keeps Traffic Moving during Large-Scale

One of the primary goals of the program was to reduce the impact on
commuter and business traffic during large-
scale construction on its road system.
Many of the bridges designed during the
early development of Oregon’s highway
system used a reinforced concrete deck girder
(RCDG) design specified in the regulations
of that time. As specifications became more
stringent in the 1960s, Oregon transitioned
to prestressed and post-tensioned concrete
bridges that improved structural integrity
at a reduced cost. Despite this, many RCDG
bridges remained in service past their expira-
tion dates and predictably began to show
signs of deterioration on deeper investigation.
“In 2001, ODOT inspectors noticed that cracks
identified in previous inspections had grown
to the point of threatening structural stabil-
ity,” said Jim Cox, assistant manager of major
projects at ODOT. “We immediately placed
load restrictions on these bridges and started
discussion on how to plan repairs with the least
impact on commercial and commuter traffic.”

In addition to these tangible benefits, ODOT experienced three

tion for reporting and responding to inquiries,” Ford said. “WZTA and
GIS in particular have resulted in improved coordination with other
agencies and interest groups, increasing the credibility of both ODOT
and the bridge program in the eyes of the public and the legislature.”
At the beginning of 2011, 351 of the 365 bridges in the OTIA III
bridge program were free of construction zone delays. WZTA played
a primary role in expediting the construction process by allowing the
team to run lane closure traffic analyses in minutes as opposed to
hours. The tool is now being used by ODOT on other roadway main-

lane closures across the state.
