mastic,

resinresin,
any of a class of amorphous solids or semisolids. Resins are found in nature and are chiefly of vegetable origin. They are typically light yellow to dark brown in color; tasteless; odorless or faintly aromatic; translucent or transparent; brittle, fracturing like glass;

 family), found chiefly in Mediterranean countries. When the bark of the tree is injured, the resin exudes in drops. It is transparent and pale yellow to green in color. Mastic is used chiefly in making varnish but is also used medicinally as an astringent and, with aniseed, to flavor a distilled liquor called mastic. The term mastic is also applied to certain caulking and adhesive compounds, especially those consisting of a mineral filler, a resinous binder (e.g., asphaltasphalt
, brownish-black substance used commonly in road making, roofing, and waterproofing. Chemically, it is a natural mixture of hydrocarbons. It varies in consistency from a solid to a semisolid, has great tenacity, melts when heated, and when ignited will burn with a smoky

mastic

Famous for it’s gum resin. Said to be the best stuff to fight H. Pylori. A shrub in the pistacio family, separate male and female plants, green year round, 3-15 ft (1-5m) high. Oval alternating leaves with light pale colored veins. Very small flowers with red “drupe” berries that turn black later. Yellow-white liquid resin that hardens in sun, can be chewed soft again in mouth. Sap drips out when tree gets small cuts on main branches. Used historically as chewing gum. Historically popular spice, used in all kinds of dishes, deserts and drinks. Used as a base for toothpaste, lotions and creams. Use as breath freshener, for lowering cholesterol, blood pressure, heart attacks, anti-bacterial, anti-fungal, skin conditions, lowering mouth plaque, peptic ulcers, H. Pylori, gastritis, duodenal ulcers

Mastic

 

(also mastic gum), a resin obtained by tapping the trunk of the mastic tree. In its hardened state it is in the form of yellowish droplets; it is very aromatic. Mastic contains essential oils (2-3 percent), resin acids (approximately 42 percent), masticic bitters (5 percent), and carbohydrate resenes (approximately 50 percent). Mastic is antiseptic owing to the presence of resin acids. It is used in the manufacture of varnishes, as a mouthwash, and as a binder in the preparation of pills and plasters.

mastic

(materials)
A glasslike, brittle, yellow to greenish yellow resinous exudation of the mastic tree (Pistacia lentiscus); used in medicine, condiments, adhesive, incense, and lacquer. Also known as mastiche; mastix; pistachia galls.
Mixture of finely powdered rock and asphaltic material used for highway construction.

In recent decades, basalt fiber has been widely utilized as a reinforcing modifier for the asphalt mastic and asphalt mixture performance [22-26].
In this paper, the thirteen different groups of diatomite and basalt fiber compound modified asphalt mastic (DBFCMAM) were studied.
The content and particle size affected the corresponding performance of asphalt mastic; consequently the penetration test data were highly discrete.
Softening point is widely utilized in the high temperature sensitivity evaluation of asphalt mastic [29].
The dynamic shear rheometer test can measure the viscosity and elastic properties of asphalt mastic at medium and high temperature.
The bending beam rheometer tests (BBR) proposed by the SHRP are widely utilized to measure the low temperature creep properties of asphalt mastic. BBR test was developed to measure the stiffness modulus of asphalt mastic and evaluate the corresponding crack resistance [32].
The creep stiffness (S) was higher and asphalt mastic was harder and quite susceptible to cracking at low temperatures.
The softening point of asphalt mastic following diatomite and basalt fiber addition was increased.
This meant that the modification with diatomite and basalt fiber made the asphalt mastic less susceptible to traffic-induced deformation at high temperatures when compared with neat asphalt mastic.
The force ductility test at 5[degrees]C was employed for the low temperature tensile property evaluation of asphalt mastic. In order for the low temperature performance of asphalt mastic to be quantitatively compared by the addition of diatomite and basalt fiber, [F.sub.max], -[D.sub.ON], and J were used for the evaluation index.
[F.sub.max] represented the tensile cohesive failure strength of asphalt mastic. It indicated that the tensile cohesive failure strength of DBFCMAM increased; therefore the low temperature tensile strength of DBFCMAM improved.
In general, when diatomite and basalt fiber content is different, the low temperature tensile property of asphalt mastic differed, but the low temperature tensile property of DBFMCAM is improved.
