Important points:

If reaction time (t) is not given assume t = 2.5sec (as per Indian Standard).
Value of ‘ g’ always = 9.81
Friction co-efficient for varuious design speed:

Speed =	<20	40	50	60	65	80	>100
f =	.40	.38	.37	.36	.36	.35	.35

Breaking Distance for Downhill or down Grade = (-x%)
Breaking Distance for Uphill or up grade = (+x%)
SSD for various lane & way are given as below:

Type of traffic	1-lane, 1-way	1-way, 2-way	2-lane, 2-way
SSD required		2xSSD	SSD

iii) Prestressed Concrete

Introduction | RCC | Engineer Ji | Civil Engineering

Reinforced concrete, as a composite material, has occupied a special place in the modern construction of different types of structures due to its several advantages.
Italian architect Ponti once remarked that concrete liberated us from the rectangle.

Good Verity of cement contains higher % of:

Tricalcium Silicate (C3S): 3CaO.SiO2

Supposed to be the best cementing material & well-burnt cement.

Dry Rot:

Reduces the timber to powder.
Dry rot is decomposition of felled timber. It is caused by the action of various fungi.
The fungus reduces fiber to a fine powder and the timber losses its strength.

परिचय | Introduction

स्वतन्त्रता प्राप्ति के बाद स्माजवादी समाज की स्थापना के लिए अर्थव्यवस्था का मिश्रित स्वरूप स्वीकार किया गया हैं, जिसमे पूंजीवादी व साम्यवादी दोनों प्रकार की अर्थव्यवस्था की कमयों को दर-किनार का इनके सकारात्मक पक्षो को स्वीकार किया गया ।
मिश्रित अर्थव्यवस्था मे सार्वजनिक व निजी क्षेत्र दोनों को उत्पादन क्षेत्र मे बराबर महत्व दिया जाता हैं ।

It may be defined as "Design of visible features of highway"
(geometric design of highway)

Syllabus to cover:

Cross- Sectional Elements
Sight Distance
Horizontal Alignment
Vertical Alignment

1) Cross- Sectional Elements:

In this article I am going to discuss the history of development of modern highways in India for JE Civil Exam (point of view).
Because, we have already learnt about Highway & Airport Engineering so, there is no need to read again, read these important points only.

Definition of Highway Engineering:

a branch of civil engineering dealing with the planning, location, design, construction, and maintenance of highways and with the regulations and control devices employed in highway traffic operations.
